I don't know if this has been asked in the past, but its a very specific question.
How important/worth it are those chrome or titanium coated AR 15 bolt carriers?

Are they really stronger than OEM, or are they just for show? the TI coated looks awesome
Thanks.:)

They are most important to the guy who is trying to lighten you wallet selling it to you.

Never had an OEM BCG fail me. Thats about all I can offer. I normally run FA carriers.

The chrome ones would probably be easier to clean, but not much else other than bling value, methinks.

I have a chrome BCG and the other AR's run the regular BCG's, never had a problem with any of them. The chrome BCG is definitely easier to clean.

My understanding is that the chrome & titanium coated AR bolt/carriers have a smoother surface that offers a smoother operation as well as they are more resistant to corrosion in the long term.

The JP QPQ coated bolt carrier groups are really nice looking. If I dump money on Goldfinger's BCG, then its gonna be the JP instead.

+1 on the JP ones looking nice, I am getting a low mass one in about 10 more weeks. Of course it is going to upper wrapped around it.

I have not purchased anything yet, but that ANVIL lower you gave me the heads-up on looks like the winner if I get enough $ next month:)

External-chromed BCGs were rejected by Uncle Sugar in late '60s since they caused excessive wear inside the upper - didn't cooperate with the CLP lube and Solid Film Lube internal coating.

Plain ol' BCG will do everyone here just fine.

Well that pretty much clears it up then:)
What about the bolt itself?, I've heard horror stories about cheaper bolts

Ah, here's a story on the matter:

There's a reason they coat cutting tools in TiN... From reading the story fallenknight posted I think if i was going to spend money on anything other than a quality standard carrier it would likely be one of the JP stainless units.

Yeah, that guy made it seem as if the DPMS part he had installed might as well
have been coated with sand!

power to weight I guess...

Gotta figure out what that trick coating is worth to you...

Basic works but can grab a little more junk and need to be cleaned more... I personally like clean guns so basic is fine for me...

One anecdotal bit of info I've heard about chromed and other such treated BCGs is that the pre-surface treatment process calls for an acid bath which can lead to a more brittle BCG, which could cause a carrier failure. Additionally, since chrome is harder than the aluminum or steel of the upper receiver, it causes accelerated wear on the upper receiver.

It does score several "looks cool" points, though.

I will use an M16 BCG when my build is complete ...:chris:

As they say in the off road world, chrome won't get you home. Chromed metal does have a tendency to be very brittle after time. my $.02 is get the basic bcg and bolt and use the left over cash to buy ammo.

Hydrogen Embrittlement http://en.wikipedia.org/wiki/Hydrogen_embrittlement can be a potential problem with high strength/hardness steels that have been chrome plated. Generally, I try to avoid chrome plating on anything but BBQ grills and DUB wheels. :)

The parkerized finish on the carrier helps hold the oil.
Neither Tin or Chrome retain oil like parkerizing.
Therefore, they tend to wear the receiver more.
My recommendation is to avoid chrome and Tin coated carriers.
